CORN-SHELLER.

SPECIFICATION forming part of Letters PatentNo. 252,594, dated January 24, 1'882.

Application filed Juno G, |881. (No model.)

To all whom it may concern Be it known that I, HENRY A. ADAMS, a citizen ofthe United States, residing at Sandwich, in th`e county ot' De Kalb and State ot' Illinois, have invented certain new and useful Improvementsin Corn-Shellers, which are fully set forth in the following speoication, reference being had to theaccompanyingdrawings,

in which- Figure 1 represents a side elevation of a portion oftheshelling devicessutlcient toillustrate in vinvention Fig. 2, a plan section of the same, taken on the line x a', Fig. l; Fig. 3, a crosssection of my im proved straight runner on an enlarged scale, taken onl the line y y, Fig. 1.

My present invention relates to an improvementin the construction ofthe shelling devices generally employed in corn-shellers, an illustration of which may be seen in a prior patent granted to me October 15, 1872, No. 132,128.

The invention consists in a bevel on the toothed face of the shelling` wheel or disk called the straight runner,77 on the outer portion of this face, so that the outer teeth will be gradually withdrawn slightly from the plane ot' the rest'of the teeth. l

The general construction ot'corn-shelling machines is so wellknown, and has been shown and described so frequently in prior patents, that it is not necessary to illustrate the entire machine in thedrawings,and therefore I have restricted my drawings to the shelling mechanism and have shown only so much of this mechanism as is necessary to a complete un derstandingofmy present improvement, which I will now proceed to describe.

In the drawings, A'represents the shelling wheelordiskcallei'lthestraightrunner.7 Two ot' them are shown, each provided on one face with the ordinary teeth or projections, ct, and both being mounted on the same shaft B. The usual bevel runners, C, two of which are shown in the drawings mounted on the'shaft D, are arranged in the ordinary relation to the straight runners.

As heretofore constructed the straight runners havehad substantially straight even faces, so that the teeth would all stand in the same plane. In my improvement theteeth a of two or three ofthe outer rows are retracted or withdrawn from the plane ofthe other teeth. This 1 accomplish by making the straight runner with a slightbevel nearits outer edge, as clearly shown in Figs. 2 and 3 ot' the drawings. The teeth a should stand perpcndicularly to the main face of the runner, the same as the other teeth; and in order to secure this result easily I make the bevel by a series ot' steps, a2, each one of which recedes a little farther than the other and carries a row of teeth. These teeth, being made of the same length as the others, will of course leave their points gradually receding from thel ,plane in which the ends of tliemain body of teeth are situated. Obviously, therefore, a flaring opening will be made between the outer portion ofthe straight runner and the bevel runner, as shown in Fig. 2 of the drawings. This is intended to obviate a difculty which has been experienced where the faces of the straight ruimer are straight, so that the teeth all lie in the same plane. It has been found that the opening between the straight runners and the bevel runners is so small that ears ot' corn, especially if somewhat damp, do not readily enter, but are thrown back. With my im provenient this difficulty is entirely removed, as the daring of the opening between the outer edge ofthe straight runner and bevel ruimer is sufcient to readily receive the end of an ear of corn, so that it will be taken at once by the teeth, after which there is no difficulty.

To provide for the beveling ofthe straight runners I have shown them with the outer portion offset, though of course the resultl may be accomplished some other way, and I do not limit myself to any parlicular mode of'making the bevel. So, too, the beveled face need not be stepped, though thisis the preferable construction in my opinion; and it' the teeth of the straight runners are quite long, it may be sut'- ticient to simply shorten thosein the outer rows without changing the plane of the disk-body.

I have shown and described what I consider the best mode ot' carrying out my invention; but I do not wish to beunderstood as limiting my improvement to the precise construction here described, but claim the right to make such modifications as suggested above and others ot' like nature.

It will of course bennderstood that in a machine having several ,holes my improvement will be applied to both faces of the bevel runners, and that it may be used in any machine having straight runners and bevel runners for its shelling mechanism.

Having thus described my invention, what I 5 claim as new, and desire to secure by Letters 1. In a corn-Sheller, a straight runner having the points of its outer teeth gradually receding, substantially as described.

1o 2. In a corn-Sheller, a straight runner provided witb gradually-receding teeth on the outer portion of its face or faces, in combination with bevel runners, substantially as and for the purpose set forth.

3. A straight runner, A, provided with a. 15 bevel in the outer portion of its face, on which are arranged gradually-receding teeth ai', substantially as described.

4. A straight runner, A. provided with a bevel on the outer portion of its face, composed 2o of a series of steps or offsets, a2, and having teeth a', arranged on these oifsets, substantially as described.
